ios - 如果用户单击 UIView 中的 "+"按钮，我如何在 UITableviewcells 中显示 UITextfields

Question

我在 UIView 中有一个“+”按钮。我的要求是，如果我单击 UITableViewCells 中显示的那个按钮 UITextFields。如果用户单击“+”按钮，我想知道如何在 UIView 中显示 UITextFields。但是我不知道如何在用户点击“+”按钮时在 UITableViewCells 中显示 UITextFields。请任何人帮助我。昨天我对这个功能感到震惊。我尝试了一些代码。但它不能正常工作。但我没有找到任何解决方案。提前致谢。

UIButton *myGreenIconButton1 = [UIButton buttonWithType:UIButtonTypeCustom];

[myGreenIconButton1 addTarget:self action:@selector(GreenIconButtonClicked)forControlEvents:UIControlEventTouchUpInside];
    [myGreenIconButton1 setBackgroundImage:[UIImage imageNamed:@"index.jpg"] forState:UIControlStateNormal];

myGreenIconButton1.backgroundColor = [UIColor clearColor];

myGreenIconButton1.frame = CGRectMake(285, 144, 25, 25);

[self.view addSubview:myGreenIconButton1];


-(void)GreenIconButtonClicked

{

   view=[[UIView alloc]initWithFrame:CGRectMake(0, 80, 300, 20)];

   text1=[[UITextField alloc]initWithFrame:CGRectMake(10, 80, 100, 20)];

   text1.borderStyle=UITextBorderStyleRoundedRect;

   text1.backgroundColor=[UIColor clearColor];

   text1.backgroundColor=[UIColor colorWithRed:0.662745 green:0.662745 blue:0.662745 alpha:0.5];

   text1.font=[UIFont systemFontOfSize:14.0];

   text1.contentVerticalAlignment=UIControlContentVerticalAlignmentCenter;

   text1.textAlignment=NSTextAlignmentCenter;

   text1.delegate=self;

   [view addSubview:text1];

   text2=[[UITextField alloc]initWithFrame:CGRectMake(120, 80, 100, 20)];

   text2.borderStyle=UITextBorderStyleRoundedRect;

   text2.backgroundColor=[UIColor clearColor];

   text2.backgroundColor=[UIColor colorWithRed:0.662745 green:0.662745 blue:0.662745 alpha:0.5];

   text2.font=[UIFont systemFontOfSize:14.0];

   text2.contentVerticalAlignment=UIControlContentVerticalAlignmentCenter;

   text2.textAlignment=NSTextAlignmentCenter;

   text2.delegate=self;

   [view addSubview:text2];

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

   static NSString *cellIdentifier = @"Cell";

   UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

   if (!cell)

   {

      cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];

   }

     [cell.textLabel setText:@""];

     [view setTag:101];

     NSIndexPath *ip = [NSIndexPath indexPathForRow:0 inSection:0];

     UITableViewCell *cell1 = [self.tableView cellForRowAtIndexPath:ip];

     UITextField *textField = (UITextField*)[cell1 viewWithTag:101];

     UITextField *textField1=(UITextField*)[cell1 viewWithTag:101];

     UITextField *textField2=(UITextField*)[cell1 viewWithTag:101];

     [cell.contentView addSubview:text1];

     [cell.contentView addSubview:text2];

     [cell.contentView addSubview:text3];

     return cell;

}
